A message from vit9696

Pleasure to meet you on this summer day. This release commemorates a second ten-version cycle for OpenCore, and we shall say that we are quite satisfied with the achievements we accomplished over the year. Big Sur support, a really tough thing, Apple Secure Boot, legacy platform support including 32-bit computers with macOS 10.4, a whole lot of visual improvements, hardware compatibility and performance fixes, documentation rewrite, usability refinements. We did way more than we planned, and are grateful to the support from our families, friends, who encouraged us and helped to find spare time, from the external contributors, who brought new features and helped to track the issues, from the community that started to build an ecosystem based on the entities we create. Thank you all for being here!

We have three major highlights for today, and our first is OpenCanopy. We worked hard to understand what the artists need from the user interface, and did our best to integrate it in a best possible way that does not contradict the OpenCore architecture. With this update a new icon concept lands in OpenCanopy. While previously the themes were limited to a small list of predefined icon names, newly introduced flavours allow arbitrary icon names that do not depend on OpenCore code and can be maintained by the community. For better understanding @MikeBeaton additionally wrote a writeup explaining the caveats and defining the initial list. Besides that, we built a new home for all the artists: OpenCanopy Gallery. While still under development, OpenCanopy Gallery already hosts a few examples and is waiting for your contributions.

Next thing to discuss are virtual machines. Virtual machines are an essential part of our everyday workflow. Those who do not use them directly may be running them indirectly. It may be slightly uncommon knowledge but modern Windows runs itself as a virtual machine. What it means for the end-user is that every modern operating system comes with a virtualisation stack. Linux and macOS come with accelerators: Hypervisor.framework and KVM accordingly. There needs to be third-party software that can utilise these mechanisms to run virtual machines, like VMware or QEMU. Windows comes with an all-in-one solution — Hyper-V. Since the amount of Windows users continues to grow, we agreed that being able to install macOS with the builtin hypervisor on Windows is a must. With thus release Goldfish64 implemented all the basics in MacHyperVSupport.

Last but not least are our continuing tests of the Z590 platform. As more boards continue to go through our hands, we discover more new issues or let’s say possibilities:

  • Since most Z590 boards have USB audio, we built a light version of our audio supplement driver — AppleALCU. This driver only has digital audio patches and is recommended for these setups.
  • Many ASUS boards for some reason fail to enable ASPM on the NVMe SSDs and GPUs. As a result one needs to inject pci-aspm-default with <02 00 00 00> value into the relevant devices and their parent bridges, when not observing the lower 2 bits, to fix the bug.
  • Disabling the IGPU via disable-gpu property may not be sufficient as it may happen late. This may result in broken sleep or DRM issues. To workaround that one can inject class-code with <FF FF FF FF> value and name with "unused" value.
  • ASMedia USB HUB used in ASUS boards to split the USB ports (e.g. 1 to 4) may immediately wake the system after sleep when working in USB 3.x mode for the first sleep attempt. This one looks extremely random and may be a bug of certain particular boards, but at the very least one can force it in 2.0 mode as a workaround.

That’s all for the highlights, see below for a complete changelog and have a nice evening.
